Can't Download 1080p with Audio

Trying to download some videos, for example: `https://www.youtube.com/watch?v=_OxLVeRP-FM` will not properly work.

The default file downloaded is 360p with audio.

When specifying 1080p or 720p, it downloads with no audio at all.

To reproduce:
```sh
ytdl https://www.youtube.com/watch\?v\=_OxLVeRP-FM --filter-resolution "(1080)?((1)720|1080)" --filter audio
```
